The science club at Hanul High School is running a project ①called "Grow Light." It tests how different colors of light affect plant growth. Each week, members place identical bean sprouts under red, blue, and white light and ②record their height. At first, many students expected the white light ③to produce the tallest plants. However, the results showed that plants under red light grew noticeably ④fast than the others. The club's advisor explained this by comparing light to food. Just as people need certain nutrients to grow strong, plants absorb certain colors of light more efficiently than others. To make the data reliable, students repeat each trial three times and calculate the average. They also keep a shared notebook, ⑤recording sunlight, watering time, and temperature.

To compensate for their carbon emissions, many individuals and companies now ①purchases carbon offsets, financial credits that fund projects such as planting trees or building renewable energy plants. The idea is appealing: paying for an equivalent amount of carbon to be absorbed elsewhere should cancel out the harm caused by activities like flying. However, critics argue that this system often ②functions as a convenient excuse for postponing genuine emission cuts rather than achieving them. For example, a newly planted forest may take decades to absorb the promised carbon, and it could later ③burn down or be cut, erasing any benefit. Moreover, some offset projects would have happened anyway, meaning the credits fund nothing truly ④additional. Therefore, relying heavily on offsets allows businesses ⑤to maintain harmful practices while appearing responsible.

Communication scholar Elisabeth Noelle-Neumann proposed the spiral of silence theory to explain why certain opinions dominate public discussion while others fade into invisibility. According to this theory, individuals constantly ②observe their surrounding environment to judge which opinions are widely accepted and which are not. When people sense that their own view belongs to a minority, they often choose ③to stay silent rather than risk social isolation or criticism. This silence, however, creates a distorted impression that the minority opinion is even rarer than it actually is, ①discouraged additional supporters from speaking up. Over time, this cycle spirals downward, allowing the dominant opinion ④to appear increasingly unanimous while dissenting voices disappear from visible conversation. Social media platforms can intensify this spiral, since visibility metrics make popular opinions instantly noticeable while unpopular ones ⑤remain hidden.

Every plastic product carries a small recycling mark, but few students know ①what these marks mean. Each symbol contains a number ②that shows what material the item is made of. Reading these marks is similar to ③reading nutrition labels on snacks, which tell you exactly what is inside. Likewise, ④throwing plastic away without checking its mark can send a reusable item straight to a landfill. Some marks even show that a material cannot be recycled at all, so it must ⑤sorted separately.

Desalination, the process of removing dissolved salts from seawater to produce fresh water, has increasingly been adopted by coastal regions facing chronic water ①scarcity. Most modern facilities rely on reverse osmosis, a technique in which seawater is forced through membranes whose microscopic pores block salt while letting water molecules pass. Because this method ②consumes far less energy than the thermal distillation once dominant in the industry, it has become the preferred choice for large-scale plants. Nevertheless, desalination remains an inherently costly and environmentally burdensome solution, a fact often overlooked amid enthusiasm for ending water shortages. For instance, the process generates a ③concentrated byproduct called brine, which, when discharged without adequate dilution, can raise local salinity to levels that harm marine life. Pumping seawater through membranes at high pressure also demands substantial electricity, so plants powered by fossil fuels can ④alleviate the emissions that intensify drought. Therefore, engineers increasingly argue that desalination should be treated not as a stand-alone remedy but as one component of a ⑤broader conservation strategy.

The Hopeful Start Workshop will be held on January 10th at the Green Hill Community Center, and this event helps students set ①clear and realistic goals for the new year. The workshop will run from two to four in the afternoon, and participants will learn simple methods for writing goals that are specific and ②easy to measure. Each participant will receive a goal-planning notebook to use throughout the year. The workshop is ③open to all middle and high school students, and no experience is required. Registration is ④free, but seats are limited to thirty people, so early sign-up is recommended, and students can register ⑤offline through the center's website or by calling the front desk before January 8th.

As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. Some policymakers initially treated internet access as a convenience, comparable to cable television, rather than as infrastructure essential to modern life. That assumption is increasingly being reconsidered, particularly as _______________. Closing this divide will require more than simply distributing devices.

Military researchers have developed weapons systems capable of identifying and engaging targets without a human pressing the final button. Advocates argue that autonomous systems can react faster than any human operator. Human rights organizations counter that removing a person from the final decision strips away moral responsibility, since _______________. Diplomatic negotiations toward an international treaty have repeatedly stalled, partly because military powers disagree on how to define autonomy precisely enough to regulate it.

주어진 문장: Thanks to her call, I felt understood and ready to try again. On the first day of winter break, my friend Yuna and I sat in a cafe and talked about the new year ahead. ( ① ) Instead of making separate plans, we decided to write our goals together on one sheet of paper. ( ② ) Yuna wanted to improve her English speaking, while I wanted to wake up earlier every morning. ( ③ ) We agreed to text each other every night to report what we had done that day. ( ④ ) At first, it felt exciting, but after two weeks, I began to feel tired and wanted to quit. Yuna noticed my short replies and called me instead of just texting. She reminded me why I had chosen this goal in the first place. ( ⑤ ) Because we supported each other through difficult moments, both of us successfully reached our goals by spring.

주어진 문장: Because the number of likes a post will receive is never guaranteed, every notification carries a small element of suspense. Psychologists have long studied a mechanism called the variable reward schedule, in which rewards arrive unpredictably rather than after every single action. ( ① ) Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. ( ② ) When someone posts a photo, they cannot predict exactly when likes will appear, nor how many they will eventually receive. ( ③ ) This uncertainty triggers a small burst of dopamine each time the phone is checked, regardless of whether the result is disappointing or thrilling. ( ④ ) Consequently, users often refresh their feeds compulsively, hoping the next check will finally bring a satisfying reward. ( ⑤ ) What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than stumbling upon them by accident. Such practices raise serious ethical questions about manipulating users' brains for profit. Therefore, people must consciously recognize this hidden mechanism and set firm limits on their checking habits.
